EN 2243-6:2005 (E) 4 Introduction This standard is part of the series of EN non-metallic material standards for aerospace applications. The general organization of this series is described in EN 4385. This standard is a level 3 document as defined in EN 4385. 1 Scope This standard defines the general requirements for the determination of shear stress and shear strain behaviour of structural adhesives by testing in tension metal to metal lap joints, at ambient or other temperatures. This method can also be used to investigate the influence of environmental exposures on structural adhesives. 2 Normative references The following referenced documents are indispensable for the application of this document.

angle of measured shear strain (in radians); d shear displacement (in millimetres); t adhesive thickness (in millimetres); F load (in newtons); L length of overlap (in millimetres); W width of overlap (in millimetres); Ge elastic shear modulus (in newtons per square millimetres). 4 Health and safety This standard does not necessarily include all health and safety requirements, associated with its use. Persons using this standard shall be familiar with normal laboratory/test house practices. It is the responsibility of the user to establish satisfactory health and safety practices and to ensure conformity with any European, national or local laws/regulations. 5 Principle/Technique Not applicable 6 Resources 6.1 Apparatus All test equipment shall be calibrated at intervals not exceeding 12 months. 6.1.1 Tensile testing machine The tensile testing machine shall conform to class 1 of EN ISO 7500-1. The failing load of the test specimen shall be within 20 % and 80 % of the upper limit of the selected loading range of the machine. 6.1.2 Suspension In order to obtain moment-free load application, a Cardanic suspension is required (see Figure 1). 6.1.3 Extensometers They shall meet the following requirements:  accuracy of test piece displacement measurement to within 0,001 mm;  measurement of test piece overlap displacement (example of three point measurement is shown in Figures 1 and 2);



EN 2243-6:2005 (E) 6  continuous recording of the load-displacement curve;  negligible influence of test piece deformation on test results. To eliminate the effect of a non-uniform adhesive layer, it is recommended to measure the overlap displacement on both sides of the test piece (see note). NOTE A correct determination of adhesive characteristics is only possible when properly measuring the adhesive layer shear deformation. Depending on the type of extensometer and its fixing to the test specimen, however, the measured value can include adherent deformations. This should be kept to a minimum. Otherwise, it is necessary to determine with the extensometer used on a dummy specimen (without adhesive layer) the adherent deformation correspo
